PARAMETERS¶

path

The path of the file to open or create.

perm

The permissions with which to create the new file. These will be ANDed with those of the parent directory by the server.

mode

The file's open mode.

DESCRIPTION¶

ixp_open and ixp_create each open a file at path. mode must include OREAD, OWRITE, or ORDWR, and may include any of the modes specified in IxpOMode(3). ixp_create, additionally, creates a file at path if it doesn't already exist.

RETURN VALUE¶

A pointer on which to operate on the newly opened file.
